Abstract
The invention discloses a kind of quality determining methods of penicillin skin test freeze dried powder, include the following steps: that (1) precision weighs Benzylpenicillin sodium salt standard items 0.02g, constant volume is dissolved with acetonitrile, it is miscible, it is made into the solution that concentration is 0.2~2mg/ml, it is stored in Brown Glass Brown glass bottles and jars only, and places and save under the conditions of 2~8 DEG C；(2) penicillin skin test freeze dried powder 0.2g is taken, it is accurately weighed, it is placed in measuring bottle in right amount, acetonitrile is added to dissolve fine powder, be settled to 2ml, shake up, filter, take subsequent filtrate as test solution；(3) it is detected using high performance liquid chromatography.Benzylpenicillin sodium salt skin test freeze dried powder quality determining method provided by the invention, specificity is strong, favorable reproducibility, it is versatile, Benzylpenicillin sodium salt main peak and auxiliary material peak can be efficiently separated, testing result is accurate, substantially increases the quality control level to penicillin skin test freeze dried powder, it is ensured that the safety of clinical application.
Description
Technical field
The present invention relates to pharmacy and Pharmaceutical Analysis technical field, and in particular to a kind of quality of penicillin skin test freeze dried powder
Detection method.
Background technique
Penicillins (Penicilins) drug is the general name of the interior phthalein amine antibiotic of a kind of β-, because its efficient, low toxicity is
Most popular one of drug is applied on clinical medicine at present, although penicillin medicine itself does not have very virulent property to body,
But easily cause drug anaphylaxis, be all kinds of allergic drugs most.The reason of penicillin allergy mainly penicillin
Catabolite penicillenic acid, penicilloic acid and its polymer, these substances as haptens enter after human body with protein
Or peptide molecule is combined into holoantigen, wherein most importantly Penicilloyl protein, it is to cause most people anaphylactoid
Main cause.Therefore, skin anaphylactic test must be first carried out in clinical application to penicillin medicine, is all China over the years
One of basic nursing routine operation, also clearly stipulate that before injection or oral penicillin class drug in Chinese Pharmacopoeia 2010 editions,
Skin test need to be carried out, the concentration of skin test medical fluid is 500 units/ml, and negative reaction person can use such drug, and during medication
When the lot number of drug has replacement, it is also necessary to reform intracutaneous test.
Data shows reagent for penicillin skin test, and from the benzyl penicillin (PG) of the first generation, the penicilloyl-to the second generation relies more
Propylhomoserin (PLL), mould thiazole carboxylic acid salt (BPNCO), solve allergic reaction, but there are still " false positive is anti-to a certain extent
Answer ", especially infant, false positive rate are up to 10.9% (Li Ya tinkling of pieces of jade " false positive of penicillin skin test 30 analyses " China
Medical Leader .2008.5 (17): 137), to analysis, judging that test results bring very big interference, the reason is that: 1.
The molecular structure of penicillin medicine determines that penicillins aqua is unstable, degradable, failure, the solution for skin test generally newly configured
Want stored refrigerated, validity period was generally within one week, and standing time is too long to be easily decomposed into the allergy such as mould thiazole and penicillenic acid
Substance；And since standing time is too long, repeatedly extract, air bubble pours into back and forth will also result in pollution, especially in summer skin
After examination, easily cause false positive reaction；2. limited by dosage form, need by repeatedly extract, mix gradually be configured to concentration be 500
Unit/ml solution for skin test (States Pharmacopoeia specifications) can use, the preparation method will cause penicillin dissolution it is insufficient, influence skin test knot
The judgement of fruit can obviously increase the false positive rate of test results, delay treatment for infant.
Furthermore the blueness of the different cultivars that circulates on domestic market, different manufacturers, different kinds of process flow, different lot numbers
Mycin drug causes the type and content of contained sensitizer different.For this reason, it may be necessary to develop a kind of more suitable penicillin
Skin test dosage form (traditional reagent for penicillin skin test, mostly injection or suspension injection), to solve the preparation stabilization of existing skin test agent
Property is poor, false positive reaction easily occur, clinical application the disadvantages of there are security risks.
The Chinese invention patent of Publication No. CN 103861125A provides novel penicillin skin test freeze dried powder and system
For technique, penicillin sodium salt 1000-10000 unit, preparation process are mainly contained in every bottle or every of skin test freeze dried powder
Be by the way that bulk pharmaceutical chemicals penicillin sodium salt is diluted with water for injection after, add the excipient of special ratios, pass through the work of optimization
Freeze dried powder is made in skill.When clinical use, a certain amount of physiological saline only need to be injected, is mixed, can be configured to concentration is 500 single
The solution for skin test of position/ml.The skin test freeze dried powder that the patent provides has preparation stability compared to traditional medical skin test agent
Well, the advantages of reducing false positive rate, be a kind of drug that traditional skin test injection is substituted with penicillins skin test freeze dried powder
Developing thought, but disadvantage is that: the related substance-measuring of skin test freeze dried powder, assay are not directed in patent
Method, and in preparation production, the content in relation to substance how is fast and accurately detected, is controlled in drug standards range
It is interior, there is very important effect safely to the industrialization and clinical application of penicillin skin test freeze dried powder.
Regrettably, the quality of penicillins skin test freeze dried powder is not yet included in " Chinese Pharmacopoeia " (2015 editions)
Detection method, pharmacopeia only provide the detection method of Benzylpenicillin sodium salt and benzylpenicillin sodium for injection, chromatographic condition are as follows: chromatographic column:
C18Column；Mobile phase A: potassium dihydrogen phosphate-methanol (72:14), Mobile phase B: acetonitrile, mobile phase A: Mobile phase B=86.5:13.5；
Flow velocity: 1mL/min；Detection wavelength: 225nm, isocratic elution.Official method is applied to Benzylpenicillin sodium salt skin test freeze-dried powder by inventor
When the quality testing of agent, there are following technological deficiencies for discovery: 1. use official method, the main peak retention time of chromatographic compared with
Short, auxiliary material peak has that overlapping, separating degree is poor with impurity peaks, and integral has interference；2. the detection architecture stability of official method is bad, inspection
Result poor reproducibility is surveyed, does not have stability indicative function.
Inventor is retrieved, and discovery is related to reagent for penicillin skin test quality testing, and pertinent literature is as follows:
Document " content of polarimetry measurement penicillin skin test injection " (Ni Hong brightness China medicine company .2008.17 (23):
33) in, a kind of content assaying method of penicillin skin test injection is disclosed, Benzylpenicillin sodium salt is measured using Polarimetry.
Document " two methods of the check experiments of benzylpenicillin skin-test solution the assay " (capital Li Cheng medicine .20007
(2) :), it discloses and carries out assay with iodimetric titration and ultraviolet spectrophotometry.
Document " stability for investigating penicillin skin test agent content " (Heilungkiang Yuan Bo, Zhang Lin, Yuan Ling medicine .2003 (1):
28-29), it discloses and assay, chromatostrip is carried out to the novocillin in reagent for penicillin skin test with high performance liquid chromatography
Part are as follows: chromatographic column: Nova-pak C18Column (3.9mm × 150nm)；Mobile phase: 0.05mol/L potassium dihydrogen phosphate-acetonitrile (4:1)；
Flow velocity: 1mL/min；Detection wavelength: 230nm；Detector scanning range: 200nm~250nm.Document discovery: skin test agent is to freeze
